"It may be a brave opinion but I predict that Ubuntu Linux and Windows Vista are going to be the two operating systems that will take over the largest chunk of the desktop OS market during the next couple of years. This comparison is based on my experience with both systems during the last couple of weeks on two different computers."

Ubuntu has an advantage, it's a household name. PCLinuxOS while it may be OK, I don't know anyone I mean ANYONE that's either heard of it or used it. I agree that Linux is capable of being a good OS for gaming, however it wasn't until this month that ATI finally released a driver that wasn't crap and that's even up in the air based on my testing.

Sure, there are a lot of how-tos on the Ubuntu forums. That means it's getting adopted. The more the better.
